Adam Kerj
Mr. Kerj comes to the New York-based shop from Publicis Groupe 's Saatchi & Saatchi in Stockholm, where he was executive creative director-founding partner. The appointment is effective immediately, though Mr. Kerj won't relocate to the U.S. with his family until this summer. He will report to 360i CEO Bryan Wiener and will oversee more than 30 people.

The establishment of a CCO post accompanies 360i's doubling in size in the past two years. It now has about 425 staffers, who work on brands such as Coca-Cola, Oreo, JC Penney and Smirnoff.

"Adam is a pioneer in identifying and implementing big ideas that solve real business challenges for his clients," Mr. Wiener said in a statement. "Marketing in the digital age requires excellence in storytelling, depth in digital and, most importantly, the ability to bring these together to guide brands where there are no roads. Adam embodies all these traits and is a great cultural fit with 360i."

Mr. Kerj was selected after dozens of interviews with candidates and a unanimous vote of confidence from 360i's senior leaders, Mr. Wiener told Ad Age . "The profile of the right CCO has changed substantially;marketers today need big, crossplatform ideas, but with digital at its core. Adam is one of the few creative leaders out there with both the digital expertise and the big-idea creative chops."

Mr. Kerj has experience working with some of 360i's clients already. During his time in Sweden, he worked on Diageo and Coca-Cola. He's also done work for other large marketers, including Toyota and Procter & Gamble. For P&G's Ariel, he created "The Fashion Shoot," a live digital event that was honored by Creativity as one of 2011's best campaigns. To see more of his work on Creativity go here.

The new role will be a big change for Mr. Kerj, who has spent the past 20 years working in European creative shops. He had a short stint at Leo Burnett in Chicago in the 1990s, but since then, he's worked at Leo Burnett in Denmark and TBWA in Sweden. He founded the Saatchi office in 2002.

Asked if he thinks that moving from a traditional creative shop to a digital agency will be a tough challenge, Mr. Kerj said: "I don't see it as that big a change, because today 50% of revenue at Saatchi Sweden comes from digital and new media. Sitting in Stockholm and watching what's going on in the world, over the last couple of years I've seen some great work coming out of agencies that didn't happen as often as it does today. New York has become more of a center of creative excellence again, and I think a lot of interesting things are happening here."
